Agilent E3610A - DC Power Supply

Agilent E3610A — DC Power Supply

0–8 V @ 3 A • 0–15 V @ 2 A • Linear Regulated • Quiet • Reliable

Purpose & Capabilities

A compact, precision linear DC power supply designed for:

• Breadboard and prototyping work

• Logic circuits

• Analog and audio electronics

• Sensor and microcontroller powering

• General bench testing

The E3610A is part of Agilent’s legendary E3600 series — known for low noise, excellent regulation, and long‑term reliability.

Access Level

• General Member Use

• No reservation required

• Only authorized volunteers may open or calibrate the unit

• Internal capacitors store dangerous energy — do not service internally

Specifications

Output Ranges

• 0–8 V @ 3 A

• 0–15 V @ 2 A

(Selectable range — the supply cannot output 15 V at 3 A.)

Performance

• Type:
  Linear regulated

• Ripple & Noise:
  Very low (millivolt‑level)

• Load Regulation:
  Excellent

• Cooling:
  Passive (silent operation)

• Output Terminals:
  Binding posts

• Protection:

  • Current limiting

  • Overvoltage protection

  • Thermal protection

Meters

• Digital readout for voltage and current

• Fast response and stable readings

Before You Begin

• Inspect the supply:

  • Ensure binding posts are clean

  • Verify leads are rated for 2–3 A

  • Check that voltage is turned down

• Select the correct range:

  • 8 V range
    for higher current

  • 15 V range
    for higher voltage

• Double‑check polarity

• Confirm your load can safely handle the selected voltage and current

Operating Guidelines

Setting Voltage & Current

• Use the coarse and fine knobs for precise control

• Set current limit before connecting your load

• Monitor front‑panel meters during operation

• Avoid sudden voltage changes on sensitive circuits

Connecting Loads

• Use proper gauge wire

• Ensure connections are secure — loose connections can arc

• For inductive loads:

  • Expect voltage dips

  • Use flyback protection if needed

During Operation

• The supply is silent — no fan

• It may get warm under load; this is normal

• Avoid running at maximum current for extended periods

After Use

• Turn voltage down to zero

• Turn off the supply

• Disconnect leads

• Coil cables neatly

Supported Use Cases

Approved:

• Breadboard circuits

• Logic circuits

• Microcontroller projects

• Audio and analog circuits

• LED drivers

• Sensor testing

• General electronics prototyping

Not approved:

• Motors

• High‑current loads

• Battery charging

• Anything requiring more than 15 V

• Experiments with exposed high‑current bus bars

Care & Etiquette

• Do not block ventilation slots

• Do not exceed the current rating of the leads

• Never intentionally short the output

• Report:

  • Output instability

  • Meter flicker

  • Burning smell

  • Excessive heating

Common Issues & Troubleshooting

• Supply drops into current limit

  • Load is drawing more current than allowed

• Voltage sag

  • Load may exceed power capability

• Output unstable

  • Check connections; inspect leads for heating

• Incorrect range behavior

  • Verify range switch position
